Answer:
the answer is k? lol thanks
Your answer would be True
Answer:
H +
Explanation:
Acid are those species which donates the H+ ion when dissolved in a solution. In other way acid are those chemical species which donate proton to other species as proton means H+ ion so H+ ions are formed as a result of dissolution ..
